IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 1 75,705, dated April 4, 1876 application filed November 16, 1875.

, point of the rake is entering the field of the platform. Fig. 2 is an elevation of the rake. Fig. 3 is a plan view, showing the position of the parts as the point of the rake is leaving the field of the platform. Fig. 4 is a bottom view of the rake, as shown in Fig. 3, and a detached section of the cam-plate.

The same letters are employed in all the figures in the indication of the same parts.

A is the platform, to which the braces B are fastened, projecting in rear to support the rake mechanism. 0 is a plate below the bottom of the platform, having on its upper face .a double-walled cam, O, to give an oscillation to the rack-bar D, which swings on a pivot, at D fastened to the brace B, and which has a This ruck engages the teeth of the segment E on the end of the arm E, pivoted to the end of the brace at the center of the segment, so that as the arm D oscillates a corresponding oscillation is given to the arm E. On the outer end of the latter is pivoted the arm F, which carries the rake, consisting of a vertical board, G, and the pointed teeth G and slotted plate (3, which extends under the bar F, and receives the friction-roller on the end of the crank-arm Hfwhich is attached to the upper end of the shaft of the cam-wheel G.

- and sweep the gavel to the'outer side of the platform, when the reverse movement of segment D will draw back the rake, and with it the gavel, until the latter falls ofi behind the platform, the stud on the crank H being drawn to the front end of the slot, and then the movement of the crank will swing the rake to its first position, the rack-bar being again nearly stationary, with only movement enough to allow the rake to make its required movement.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the oscillating rackbar D, arm E, and segment E, arm F, slot G and crank H, for sweeping the rake over the platform, substantially as set forth.

2. In combination with an arm, E, pivoted to the end of the rake-arm F, and oscillating rack-bar D, to project and retract it, the crank H, having stud on its outer end engaged with a slot in the rake-arm, to give it transverse movement across the platform. while it allows the other movement, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PLINY F. HODGES.
